This tutorial is now available as the Amahi [https://www.amahi.org/apps/postfix-mail-relay Post Mail Relay] application. This can be used to send mails from your Amahi 7 or greater (Fedora 19/Amahi 7 or greater) HDA and to receive system emails. To receive emails meant for the root user, you have to [[Forward_System_Emails|Forward System Emails]] after finishing this tutorial. You also might want to take a look at [[Masquerade_email_address|Masquerade email address]] as well.<br>

<pre>postmap hash:/etc/postfix/sasl_passwd</pre>
* Create /etc/postfix/tls_policy file with your Gmail login credentials that looks like below:
<pre>[smtp.gmail.com]:587 encrypt</pre>
<br />
<pre>chmod 600 /etc/postfix/sasl_passwd
chmod 600 /etc/postfix/sasl_passwd.db
chmod 600 /etc/postfix/tsl_policytls_policychmod 600 /etc/postfix/tsl_policytls_policy.db</pre><!--
chown postfix /etc/postfix/sasl_passwd
chown postfix /etc/postfix/sasl_passwd.db
<b>NOTE:</b> Some ISPs will block emails sent using this method. Looking for a work around.
== Troubleshooting ==
* If you get the message " warning: SASL authentication failure: No worthy mechs found", install this package.
yum install cyrus-sasl{,-plain}
:Restart Postfix
systemctl restart postfix
* Receive the following message:
connect to smtp.gmail.com[2607:f8b0:400e:c05::6d]:587: Network is unreachable
:To correct this problem, change /etc/postfix/main.cf as follows:
inet_protocol = ipv4
:Restart postfix
systemctl reload postfix
